I'm a Metroid whore so disregard most of what I say but I'm definitely liking the change of pace in Other M (outside of the retardo title). The Primes were getting boring and stiff. The puzzles were straight forward and the gameplay felt muddy. It felt like running around under water. The weirdo soundtrack was pretty beat too.
Other M is more action oriented and the gameplay and cut scenes flow in and out of each other without any seams. The soundtrack is far better than the goopy, moody stuff coming out of Prime. There are far more entertaining challenges and enemies around every corner making for some very intense action. It's like fighting a mini-boss every 15 minutes. Very cool, IMO.
I'm stearing clear of Galaxy 2. I don't feel like playing that same tired game. I hated the fucked up camera angles too. Fuck Galaxy. I want another entry in the Super Mario World series.
